API standard 650 self-anchored tank joints

Natural ventilation loss: the main cause of natural ventilation loss is that the API standard 650 self-anchored tank is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API standard 650 self-anchored tank is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.

When as-rolled plate material complies with impact test requirements as specified here, the material need not be normalized. If, as with ASTM A516, the specification prohibits impact test without normalizing but otherwise permits as-rolled plates, the API 620 welded storage tanks material may be ordered in accordance with the above provision and identified as “MOD” for this API modification.

The standard API 650 covers the design and calculation of different parts of the API standard 650 self-anchored tank fuel tank. This specification is based on the knowledge and experience of buyers, manufacturers and users of API 650 welded storage tanks of different sizes and capacities. It is worth noting that the code requirements are minimal; stricter standards can be adopted for specific applications.
